Incorporating user search behaviour into relevance feedback [PDF]
, 2003 In this paper we present five user experiments on incorporating behavioural information into the relevance feedback process. In particular we concentrate on ranking terms for query expansion and selecting new terms to add to the user's query.

A survey on the use of relevance feedback for information access systems [PDF]
, 2003 Users of online search engines often find it difficult to express their need for information in the form of a query. However, if the user can identify examples of the kind of documents they require then they can employ a technique known as relevance ...

Patent query reduction using pseudo relevance feedback [PDF]
, 2011 Queries in patent prior art search, being full patent applications, are very much longer than standard ad hoc search and web search topics. Standard information retrieval (IR) techniques are not entirely effective for patent prior art search because of ...

Query expansion for language modeling using sentence similarities [PDF]
, 2011 We propose a novel method of query expansion for Language Modeling (LM) in Information Retrieval (IR) based on the similarity of the query with sentences in the top ranked documents from an initial retrieval run.

Query dependent pseudo-relevance feedback based on wikipedia [PDF]
, 2009 Pseudo-relevance feedback (PRF) via query-expansion has been proven to be effective in many information retrieval (IR) tasks. In most existing work, the top-ranked documents from an initial search are assumed to be relevant and used for PRF.

A Study of Word Bigrams for Pseudo-relevance Feedback in Information Retrieval [PDF]
Journal of Universal Computer ScienceTraditional information retrieval models mostly adopt a term independence assumption and are based on single terms or unigrams. Past efforts have attempted to go beyond this assumption, such as by using contiguous terms (i.e.

Retrieval through explanation : an abductive inference approach to relevance feedback [PDF]
, 1999 Relevance feedback techniques are designed to automatically improve a system's representation of a query by using documents the user has marked as relevant.

A user profiles acquiring approach using pseudo-relevance feedback [PDF]
, 2009 User profiles are important in personalized Web information gathering and recommendation systems. The current user profiles acquiring techniques however suffer from some problems and thus demand to improve.

The use of implicit evidence for relevance feedback in web retrieval [PDF]
, 2002 In this paper we report on the application of two contrasting types of relevance feedback for web retrieval. We compare two systems; one using explicit relevance feedback (where searchers explicitly have to mark documents relevant) and one using implicit

Improving Pseudo-Relevance Feedback With Neural Network-Based Word Representations
IEEE Access, 2018 In information retrieval, query expansion methods, such as pseudo-relevance feedback, are designed to enrich users' queries with relevant terms for comprehensively interpreting the desired information.
